i made a box for my Atlas but i think it may have a leak, i threw it together in an hour. i made it pretty wide and shallow, for my next box i was thinkin about making the width skinnier and depth deeper. does this make a difference or does it not matter the shape as long as the box volume is at the recommended volume?
when you built the box, did you caulk the inside seams of the box? and i don't think it makes that much of a difference, but i wouldn't build a box that was long and skinny.
